In use to set up the portable center hub slide-way enclosure system of the present invention two different embodiments require two different procedures. The steps for setting up a stand alone enclosure are as follows:

-   1) Take enclosure out of bag/backpack, which may be used for     storage. -   2) Telescope out (or fold out or attach chain-corded) ceiling poles     or structural supports to their full extended length. It could be     more than one tear but drawings only show one. -   3) With two people: Each person grabs poles from each side of the     upside down ‘L’ shaped closed position and start walking/fanning all     poles (with covers attached) out towards one another on the opposite     end until the two people meet each other resulting in a fully fanned     out enclosure. -   4) One person zips the zipper of the ceiling cover closed down to     the bottom of the ceiling cover (FIG. 10) and/or to the bottom of     the sidewall cover (FIG. 1). -   5) Telescope up (or fold out or attach chain-corded) sidewall (leg)     poles to their full extended length. -   6) If a floor covering is used; close the zipper(s) on the floor     cover. Reverse the above for storing away.

The steps for setting up a portable center hub slide-way enclosure as a connected extension of a building structure: are as follows:

-   1) Take enclosure out of bag/backpack. -   2) Telescope out ceiling poles sections of the structural supports,     then sidewall (leg) poles sections of the structural supports. -   3) Attach one pole to the building structure if storing in an upside     down ‘L’ shape or attach one pole from each widths end if storing in     an upside down ‘U’ shape (see drawings in next email.) -   4) There will be a strap that wraps around ‘all poles’ that is     attached to the building structure so all poles are secured in place     when stored adjacent to building. -   5) One person unleashes the strap(s) and grabs the poles and walks     outward so enclosure fans out to a full open position. -   6) Latch the last pole to the side of the building when using the     upside down “L” shape form for full open position. When using the     upside down “U” shape form, then two people fan poles towards one     another and then have one person zip the ceiling cover closed and if     side wall used zip that closed.
